Active clinical trials for "Recurrence"

This study aims at exploring whether plasma radiofrequency ablation at low temperature is associated with better survival outcome in localized recurrent nasopharyngeal carcinoma by conducting a randomized controlled trial of plasma radiofrequency ablation at low temperature versus electrocautery block resection at high frequency for localized recurrent nasopharyngeal carcinoma. If the hypothesis is confirmed, it is expected to provide a convenient choice for the surgical treatment of localized recurrent nasopharyngeal carcinoma.

A prospective study of partial breast re-irradiation in patients with local recurrence of breast cancer

A sample of participants' T cells will be sent to a laboratory, where the cells will be made into the study therapy, MCARH109 and MCARH125. Participants will receive either MCARH125 alone or MCARH125 with MCARH109.

This is a single-arm, non-randomized study of re-irradiation of diffuse intrinsic pontine glioma (DIPG)

This study is a single arm, open, multi center phase II exploratory study. To evaluate the efficacy and safety of AK105 combined with androtinib hydrochloride capsule in patients with relapsed/refractory classical Hodgkin's lymphoma (relapse or progression after autologous stem cell transplantation, or relapse progression after autologous stem cell transplantation but ≥ 1 line systemic multi drug combination chemotherapy). After screening, the subjects met the inclusion criteria and did not meet the exclusion criteria, and then entered the treatment period. They received AK105 injection (once every three weeks, 200mg/time, intravenous infusion) combined with androtinib hydrochloride capsule (once a day, 10mg each time, and stopped for one week for two consecutive weeks). Every 21 days was a treatment cycle until disease progression/intolerance occurred or the sponsor terminated the study. Patients with complete remission (CR) continue to receive 4 cycles of treatment, and then further consolidate treatment every 9 weeks within 1 year of continuous CR, and can stop treatment after 1 year of continuous CR. At the end of the trial, the subjects who can still benefit from the study treatment as judged by the investigator will continue to be provided with the trial drug. The longest administration time of AK105 combined with androtinib hydrochloride capsules shall not exceed 2 years.

This ComboMATCH patient screening trial is the gateway to a coordinated set of clinical trials to study cancer treatment directed by genetic testing. Patients with solid tumors that have spread to nearby tissue or lymph nodes (locally advanced) or have spread to other places in the body (advanced) and have progressed on at least one line of standard systemic therapy or have no standard treatment that has been shown to prolong overall survival may be candidates for these trials. Genetic tests look at the unique genetic material (genes) of patients' tumor cells. Patients with some genetic changes or abnormalities (mutations) may benefit from treatment that targets that particular genetic mutation. ComboMATCH is designed to match patients to a treatment that may work to control their tumor and may help doctors plan better treatment for patients with locally advanced or advanced solid tumors.

Orthodontic treatment goals can be expressed as achieving ideal tooth alignment, esthetic, functional occlusion and stability. Various occlusal changes occur after active phase of orthodontic treatment, these unwanted changes are called relapse. Reitan pointed out that major percentage of changes following active phase of treatment is seen within 24 hours. To alleviate the effect of relapse, retention is needed. There is little agreement among clinicians about orthodontic retention protocol due to insufficient evidence in the literature on 1. time of retainer delivery 2. unexpected post- treatment changes. 3.quantification of relapse tendency. The present study will be undertaken to assess the changes and compare if there is any difference in the movement of teeth in post orthodontic treatment cases with immediate and delayed (post 24 hours) retainer delivery. Thus help in deciding when should the retainer delivery is preffered.

The goal of this clinical trial is to assess the efficacy of the probiotic Limosilactobacillus reuteri 3613 for the decrease or prevent UTI occurrence in women ages 18-65 with a confirmed medical history of recurrent uncomplicated UTIs compared to a Placebo (the study medication without the probiotic)

This phase II trial studies how well dynamic susceptibility contrast-enhanced magnetic resonance imaging (DSC-MRI) works in measuring relative cerebral blood volume (rCBV) for early response to bevacizumab in patients with glioblastoma that has come back. DSC-MRI may help evaluate changes in the blood vessels within the cancer to determine a patient?s response to treatment.

The aim of this study is to evaluate the effectiveness and safety of intravesical gemcitabine instillation during operation to prevent intravesical recurrence after radical nephroureterectomy in upper urinary tract urothelial carcinoma.
